摘要
目的:观察郑州市区恒牙期安氏Ⅰ类错女性牙颌颅面结构形态特征。方法:收集来自郑州市区的41例恒牙期安氏Ⅰ类错女性治疗前X线头颅定位片,用Winceph8.0头影测量分析软件选用Steiner分析法对其有关角度、线距进行测量,并分别与正常值进行比较。结果:患者SNA、SNB、SND和SL较正常值小,U1-NA(mm)、U1-NA、GoGn-SN、OP-SN和SE较正常值大,差异均具有统计学意义(P<0.05)。结论:郑州市区恒牙期安氏Ⅰ类错女性颅颌面骨骼深度增加;为垂直向生长型,下颌顺时针旋转,呈Ⅱ类侧貌特征。
Aim：To investigate the craniofacial morphology characteristics of permanent dentition females with Class Ⅰ malocclusion in Zhengzhou.Methods：A total of 41 cases of cephalograms of untreated females of Han nationality in Zhengzhou with Class Ⅰ malocclusion were collected.The Winceph 8.0 cephalometric software and Steiner analysis methods were used.The parameters were compared with those of the normal occlusion ones.Results：Compared with normal occlusion,the parameters which were lower were SNA,SNB,SND angles,and the length of SL,and the parameters which were higher were the length of U1-NA and SE,the angle of U1-NA,GoGn-SN and OP-SN（P0.05）.Conclusion：The depth of craniofacial skeleton in Class Ⅰ has increased;the females possess Class Ⅱ profile morphological characteristics own to the vertical growth style and clockwise rotated mandible.
